PERCY T. GILBERT, OF DULUTH, MINNESOTA.

PLIERS.

Application filed June 5,

To all whom 2'25 may concern:

Be it known that I, PERCY T. GILBERT, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Pliers, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

his invention relates to hand instruments and has special reference toan improved form of pulling pliers for removingterminal connections onstorage batteries or the like, such, for example, as tip or clampterminals.

The advantages of some such tool for the manipulation of terminals onbatteries or similar equipment is well known to those familiar with therepair of lighting or starting systems on automobiles, it frequentlybeing quite hard to accomplish the removal or application of electricconnections with ordinary tools at hand, though my present invention isan admirable tool for the purpose and is also convenient ofmanipulation;

- the same being the primary object of the invention.

Referring to the accompanying drawings:

Figure 1 is an elevation of my improved pliers as applied to a tipterminal in the act of disconnecting same;

Figure 2 is a similar view of the jaws of the pliers as applied to aclamp terminal; and

Figure 3 is a similar view to Figure 2 showing the instrument applied toa modified form of terminal.

The invention broadly relates to a modified form of the jaws of thecommon adjustable pincers, the overhang jaw of which is illustrated at 1and the shorter jaw at 2, the latter being preferably wedge shaped forengaging an object in confined quarters.

In the extreme lip 3 of the overhang jaw is installed a thumbscrew 4:,it being susceptible to adjustment either substantially towards or awayfrom the other jaw so as 1922. Serial N0. 565,833.

to be able to reach into an aperture, such as illustrated at 5 in Figure1 for the purpose of engaging the end of the male member of the terminalfor the purpose of pushing against same when the lip 6 0f the shorterjaw is impinging a portion of the terminal which it is desired to movein the opposite direction to that of the male portion; such conditionsbeing common in what is called a tip terminal connection on a storagebattery.

In the event of the pliers being used on a clamp terminal as shown inFigure 2, it may not be at all necessary to make use of the thumbscrew4:, as each jaw will directly impinge its relative part of the terminalwhich istobe moved in the opposite direction to that engaged by theother jaw. However, it is quite obvious that the essential feature apartfrom the specific construction of the jaws is that one is considerablyshorter than the other.

From the foregoing it is evident that I have devised an exceedinglysimple and inexpensive puller which it appears every battery repairmanwould appreciate as it pro vides a tool for the complete adjustment ofthe battery connection of an automobile, and is convenient for theadjustment of other devices requiring relatively small contrac tion orexpansion.

Having thus described my invention what is claimed as new and desired tosecure by Letters Patent is:

A pair of pliers of the character described having jaws of unequallength and an adjustable thumbscrew within the extreme outer lip of thelonger jaw, whereby an object may be engaged by the thumbscrew beyondthe limits of the shorter jaw.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
